Title: Production of fine powder of zirconium oxide
Inventor: ABE HIDEKI
IPC: C01G25/02
Filed: 1982-12-14
Abstract: PURPOSE:An aqueous solution of zirconium salt is controlled in its pH, Zr concentration and sulfate ion concentration to effect the preipitation of an insoluble Zr salt and the precipitate is converted into the hydroxide with an alkaline substance, then dried and roasted to produce fine particles of ZrO2 with uniform particle size. CONSTITUTION:An aqueous solution of a Zr salt containing ZrO2 is controlled so that its pH becomes 0-2.5, its concentration becomes 0.1-2.0mol/l and the SO4<-->/Zr molar ratio ranges from 0.1-1.0. The resultant aqueous solution is heated, when necessary, and the reaction is effected under stirring to form an insoluble Zr salt containing sulfate ion. The precipitate is washed and converted into its hydroxide by reaction with an alkaline substance such as aqueous ammonia, then the hydroxide is dried, crushed and roasted. The process gives fine particles of ZrO2 of almost spherical form, thus showing good dispersibility.

Filed: 1999-08-02
Abstract: PROBLEM TO BE SOLVED: To enable heat exchange of a high-temperature exhaust gas and to prevent a corrosion of a heat transfer tube due to the gas by providing a shielding wall between a flow passage in a shell and a periphery of a body of the tube, and using the wall as a corrosion preventing means of an outer wall of the tube body. SOLUTION: The heat exchanger 10 comprises a shell 20, a cold air header 30, a hot gas header 50, a plurality of heat transfer tubes 40 and a shielding wall 60. The wall 60 is formed by stacking many heat resistant and heat conductive block members 61 to form a cylindrical space between a flow passage 15 of an exhaust gas A in the shell 20 and a tube body 45 of the tube 40. An air B to be preheated is passed through the body 45 of the tube from an inlet 33 of the header 30, and exhausted from an exhaust port 53 of the header 50. The gas A is heat exchanged with the air B while passing through the passage 15. Thus, since the gas A is not brought into direct contact with the tube 40, a corrosion of the tube 40 is prevented.

The drum can 1 is rotated one turn in succession thereto. The drum can is paused for a specified length of time at every rotation of 60 deg. and the integrated values of counting of Co-60, Cs-137 and the external ray source 22 are determined by germanium detectors 2a, 2b during this time. The 2nd stage of the drum can 1 is similarly measured. The rotation and rise of the drum can 1 are repeated until finally the lowermost stage of the drum can 1 is measured. The measurement with high accuracy is enabled by constituting the method in such a manner even if the concn. of the nuclide is nonuniform.

Title: Focal state inspecting device
Inventor: TANAKA SHINICHI
IPC: G11B7/08
Filed: 1984-10-18
Abstract: PURPOSE:To inspect with high accuracy the focal state of an optical information reproducing device by providing a reproducing head for reading the information and outputting an information signal, and a counting means for counting for a prescribed time the number of times by which a state inversion interval of the information signal is shorter than a prescribed length. CONSTITUTION:A read signal which is read by a reproducing head 1 is waveform- shaped by a waveform shaping means 11, and an inversion interval is measured by an inversion interval detecting means 12. A counting means 13 is cleared by a clock of an output from a clock generating means 14, and counts the number of pulses generated before the next clock. When a focal state is deteriorated, an inter-symbol interference of the time of reading a digital signal increases. When the inter-symbol interference increases, the minimum inversion interval is further shortened, and when the focal state is deteriorated, many inversion intervals being shorter than a prescribed length which is set to the minimum inversion interval or so appear. Accordingly, the counting number of the counting means 13 increases or decreases in accordance with the focal state, and when the focal state is the best state, the number of times of counting becomes minimum, therefore, the focal state can be inspected by the said number.

Afterwards, the counter 101 performs count down. A processing is completed at a time when the output of the counter 101 goes to the minimum value by repeating the above operation. By performing such processing, the memories 105 and 106 store the left and the right end of the level set in the fuzzy set B. In such a way, it is possible to perform the fuzzy inference by the indirect method.

Title: Operating method of blast furnace
Inventor: ICHIDA MORIMASA
IPC: C21B5/00
Filed: 1983-11-22
Abstract: PURPOSE:To control adequately the flow of gas ascending in a blast furnace and to stabilize the condition of the blast furnace by measuring the size of the coke sample in the tuyere in the stage of operating the blast furnace and adjusting the speed of the hot air in the tuyere from the size thereof. CONSTITUTION:The coke sample in the surface layr part of the furnace core from the top end part of the raceway in a blast furnace is drawn through a tuyere during the operation of the blast furnace. The size of the coke is measured and when the coke having <=3mm. grain size attains >=5% % by weight, the rate of ventilation is decreased on account of formation of coarse grains of the raw material at the furnace core. As a result, smaller rate of ventilation than the decending speed of the raw material in the wall part is obtained and the uniform descending is not possible. The speed of the hot air to be blown through the tuyere is made <=200m/sec in such a case by which the fine particles of <=3mm. in the coke in the furnace is made <=5% and the descending speed of the raw material in the furnace is made uniform. The furnace condition is thus stabilized.

The positioning of the direct-acting stages 6, 8 is controlled by using laser beams applied to the mirror 5 for the laser interferometer at a preceding time, the attitude of the mirror 5 for the laser interferometer is measured again, and a second measured value is obtained. The quantity of the variation of the attitude of the mirror 5 for the laser interferometer is computed on the basis of the first and second measured values at the preceding time, and the tilt stage 7 is controlled on the basis of the quantity of the variation of the attitude at the preceding time in order to correct an Abbe error. When the quantity of the variation of the attitude at the preceding time is kept outside a specified tolerance, the tilt stage 7 is controlled on the basis of the quantity of the variation of the attitude.
